Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery if working on electronic systems.

2. Tire Inspection and Replacement

Sub-steps:
- Check tire pressure and inflate to manufacturer specifications.
- Inspect tire tread depth; replace tires if tread is below 2/32 inch.
- If tires are worn unevenly, consider rotating or replacing as necessary.
Tools Required: Tire pressure gauge, tire tread depth gauge, jack, jack stands, lug wrench.

3. Suspension and Alignment Check

Sub-steps:
- Inspect suspension components such as struts, shocks, and bushings for any visible damage.
- Check wheel alignment; if misaligned, perform an alignment adjustment.
- Replace any worn or damaged suspension components following manufacturer specifications.
Tools Required: Alignment machine, socket set, torque wrench.

4. Traction Control System Reset

Sub-steps:
- If DTCs indicate a traction control fault, clear the codes using the OBD-II scanner.
- Test drive the vehicle to ensure the traction control system functions correctly.
- If issues persist, further diagnostics on the traction control module may be necessary.
Tools Required: OBD-II scanner.
